To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—personal safety instruction. Failure to comply with the instruction may result in personal injury or death. • Establish your own special procedures and work rules for unusual operating conditions (e.g. slopes too steep for sprayer operation). • Make sure that operators are thoroughly trained and familiar with the Operator’s Manual, Engine Manual, and all labels on the sprayer. Chemical Safety Supervisors, operators, and service persons should be familiar with the following standards and publications: (The material may be obtained from the address shown). Chemicals are hazardous and can injure you, bystanders, animals, plants, soils, or other property. • Flammable and Combustible Liquids Code: ANSI/NFPA 30 • Carefully read and follow the chemical manufacturer’s instructions for the safe preparation, use, and disposal of the chemical. • National Fire Protection Association: ANSI/NFPA #505; Powered Industrial Trucks National Fire Prevention Association Barrymarch Park Quincy, Massachusetts 02269 U.S.A. • Keep chemicals off of your or bystander’s skin. If contact should occur, wash it off immediately with clean water and detergent. • SAE 2258 Light Utility Vehicles Society of Automotive Engineers SAE World Headquarters 400 Commonwealth Drive Warrendale, PA 15096-0001 • Wear goggles and other protective equipment as instructed by the chemical manufacturer. • Obtain proper training before using or handling chemicals. • ANSI/UL 558; Internal Combustion Engine Powered Industrial Trucks American National Standards Institute, Inc. 1430 Broadway New York, New York 10018 U.S.A. or Underwriters Laboratories 333 Pfingsten Road Northbrook, Illinois 60062 U.S.A. • Use the correct chemical for the job. • Follow the chemical manufacturer’s instructions for the safe application of the chemical. • Handle chemicals in a well ventilated area. • Wear goggles and other protective equipment as instructed by the chemical manufacturer. Ensure that as little skin as possible is exposed while using chemicals. Safe Operating Practices • Have clean water available especially when filling the spray tank. • Do not eat, drink, or smoke while working with chemicals. The sprayer is an off-highway vehicle only and is not designed, equipped, or manufactured for use on public streets, roads, or highways. • Always wash your hands and other exposed areas as soon as possible after finishing the work. 4 • Properly dispose of unused chemicals and chemical containers as instructed by the chemical manufacturer and your local codes. • Chemicals and fumes in the tanks are dangerous; never enter the tank or place your head over or in the opening. • Be extremely careful when operating around people. Always be aware of where bystanders might be and keep them away from the work area. • Before operating the sprayer, always check the designated areas of the sprayer that are stated in the Pre-Starting Checks in the Operation section. If the machine does not function correctly or is damaged in any way, do not use the sprayer. Make sure that the problem is corrected before the sprayer or attachment is operated. Before Operating • Operate the machine only after reading and understanding the contents of this manual. • Never allow children to operate the sprayer. Anyone who operates the sprayer should have a motor vehicle license. • Never allow other adults to operate the sprayer without first reading and understanding the Operator’s Manual. Only trained and authorized persons should operate this sprayer. Make sure that all operators are physically and mentally capable of operating the sprayer. • This sprayer is designed to carry only you, the operator. Never carry any passengers on the sprayer. • Never operate the sprayer when under the influence of drugs or alcohol. Even prescription drugs and cold medicines can cause drowsiness. • Do not drive the sprayer when you are tired. Be sure to take occasional breaks. It is very important that you stay alert at all times. • Become familiar with the controls and know how to stop the engine quickly. • Keep all shields, safety devices, and decals in place. If a shield, safety device, or decal is malfunctioning, illegible, or damaged, repair or replace it before operating the machine. • Always wear substantial shoes. Do not operate the machine while wearing sandals, tennis shoes, or sneakers. Do not wear loose fitting clothing or jewelry which could get caught in moving parts and cause personal injury. • Wearing safety glasses, safety shoes, long pants, and a helmet is advisable and required by some local safety and insurance regulations. • Avoid driving when it is dark, especially in unfamiliar areas. If you must drive when it is dark, be sure to drive cautiously, use the headlights, and even consider adding additional lights. • Ensure that all fluid line connectors are tight and all hoses are in good condition before applying pressure to the system. • Since gasoline is highly flammable, handle it carefully. – Use an approved gasoline container. – Do not remove the cap from the fuel tank when the engine is hot or running. – Do not smoke while handling gasoline. – Fill the fuel tank outdoors, and fill it to about 1 inch (25 mm) below the top of the tank (the bottom of the filler neck). Do not overfill it. – Wipe up any spilled gasoline. While Operating Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area. • The operator should remain seated whenever the sprayer is in motion. The operator should keep both hands on the steering wheel whenever possible. Keep your arms and legs within the sprayer body at all times. • Always watch out for and avoid low overhangs such as tree limbs, door jambs, and overhead walkways. Make sure there is enough room over head to easily clear the sprayer and your head. 5 • Failure to operate the sprayer safely may result in an accident, tip over of the sprayer, and serious injury or death. Drive carefully. To prevent tipping or loss of control: – Use extreme caution, reduce speed, and maintain a safe distance around sand traps, ditches, creeks, ramps, unfamiliar areas, or any areas that have abrupt changes in ground conditions or elevation. – Watch for holes or other hidden hazards. – Use extra caution when operating the sprayer on wet surfaces, in adverse weather conditions, at higher speeds, or with a full load. Stopping time and distance will increase with a full load. – Avoid sudden stops and starts. Do not go from reverse to forward or forward to reverse without first coming to a complete stop. – Slow down before turning. Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of sprayer control. – Before backing up, look to the rear and ensure that no one is behind you. Back up slowly. – Watch out for traffic when you are near or crossing roads. Always yield the right of way to pedestrians and other vehicles. This sprayer is not designed for use on streets or highways. Always signal your turns or stop early enough so that other people know what you plan to do. Obey all traffic rules and regulations. – The electrical and exhaust systems of the sprayer can produce sparks capable of igniting explosive materials. Never operate the sprayer in or near an area where there is dust or fumes in the air which are explosive. – If you are ever unsure about safe operation, stop work and ask your supervisor. • Do not touch the engine or muffler while the engine is running or soon after it has stopped. These areas may be hot enough to cause burns. • If the machine ever vibrates abnormally, stop immediately, wait for all motion to stop, and inspect the sprayer for damage. Repair all damage before resuming operation. • Before getting off of the seat: 1. Stop the movement of the machine. 2. Place the range selector in Neutral and set the parking brake. 3. Turn the ignition key to Off. 4. Remove the ignition key. Note: If the sprayer is stopped on an incline, block the wheels after getting off the sprayer. Braking • Slow down before you approach an obstacle. This gives you extra time to stop or turn away. Hitting an obstacle can damage the sprayer and its contents. More important, it can injure you. • Gross Vehicle Weight (GVW) has a major impact on your ability to stop and/or turn. Heavy loads and attachments make a sprayer harder to stop or turn. The heavier the load, the longer it takes to stop. • Turf and pavement are much more slippery when they are wet. It can take 2 to 4 times as long to stop on wet surfaces as on dry surfaces. If you drive through standing water deep enough to get the brakes wet, they will not work well until they are dry. After driving through water, you should test the brakes to make sure they work properly. If they do not, drive slowly while putting light pressure on the brake pedal. This will dry the brakes out. Operating on Hills and Rough Terrain Operating the sprayer on a hill may cause tipping or rolling of the sprayer, or the engine may stall and you could lose headway on the hill. This could result in personal injury. • Do not accelerate quickly or slam on the brakes when backing down a hill, especially with a load. • Never drive across a steep hill; always drive straight up or down or go around the hill. • If the engine stalls or you begin to lose headway while climbing a hill, gradually apply the brakes and slowly back straight down the hill. • Turning while traveling up or down hills can be dangerous. If you have to turn while on a hill, do it slowly and cautiously. Never make sharp or fast turns. 6 • Heavy loads affect stability. Reduce the weight of the load and your speed when operating on hills. • Avoid stopping on hills, especially with a load. Stopping while going down a hill will take longer than stopping on level ground. If the sprayer must be stopped, avoid sudden speed changes, which may initiate tipping or rolling of the sprayer. Do not slam on the brakes when rolling backward, as this may cause the sprayer to overturn. • The Toro Company strongly recommends installing the optional ROPS Kit when operating on hilly terrain. If you install a ROPS, always wear the seat belt when driving the sprayer. • Reduce speed and load when operating on rough terrain, uneven ground, and near curbs, holes, and other sudden changes in terrain. Loads may shift, causing the sprayer to become unstable. Do not suddenly apply the brakes. Use extra caution on slopes. • Be aware that heavy loads increase your stopping distance and reduce your ability to turn quickly without tipping over. Maintenance • Only permit qualified and authorized personnel to maintain, repair, adjust, or inspect the sprayer. • Before servicing or making adjustments to the machine, stop the engine, set the parking brake, and remove the key from the ignition to prevent someone from accidentally starting the engine. • To make sure that the entire machine is in good condition, keep all nuts, bolts, and screws properly tightened. • To reduce the potential for fire, keep the engine area free of excessive grease, grass, leaves, and accumulation of dirt. • Never use an open flame to check the level or leakage of fuel or battery electrolyte. Sudden changes in terrain may cause abrupt steering wheel movement, possibly resulting in hand and arm injuries. • If the engine must be running to perform a maintenance adjustment, keep your hands, feet, clothing, and any parts of your body away from the engine and any moving parts. Keep everyone away. • Reduce your speed when operating on rough terrain and near curbs. • Grip the steering wheel loosely around the perimeter. Keep your hands clear of the steering wheel spokes. • Do not use open pans of fuel or flammable cleaning fluids when cleaning parts. • Do not adjust the ground speed governor. To ensure safety and accuracy, have an Authorized Toro Distributor check the ground speed. Loading The weight of the cargo can change the sprayer center of gravity and sprayer handling. To avoid loss of control and personal injury, follow these guidelines: • Reduce the weight of the load when operating on hills and rough terrain to avoid tipping or overturning of the sprayer. • Liquid loads can shift. This shifting happens most often while turning, going up or down hills, suddenly changing speeds, or while driving over rough surfaces. Shifting loads can cause the sprayer to tip over. • When operating with a heavy load, reduce your speed and allow for sufficient braking distance. • Keep your body and hands away from pin hole leaks or nozzles that eject high pressure fluid. Use cardboard or paper to find leaks. Fluid escaping under pressure can penetrate skin and cause injury requiring surgery within a few hours by a qualified surgeon or gangrene may result. • If major repairs are ever needed or assistance is required, contact an Authorized Toro Distributor. • To be sure of optimum performance and safety, always purchase genuine Toro replacement parts and accessories.

Voltmeter Hour meter Vehicle controls Accelerator Pedal Brake Pedal The accelerator pedal (Figure 11) gives you the ability to vary ground speed of the sprayer. Pressing the pedal increases ground speed. Releasing the pedal will slow the sprayer and the engine will idle. Use the brake pedal to stop or slow the sprayer (Figure 11). Brakes can become worn or can be adjusted incorrectly resulting in personal injury. If brake pedal travels to within 1 inch (2.5 cm) of the sprayer floor board, the brakes must be adjusted or repaired. Parking Brake The parking brake is a large lever to the right of the seat. (Figure 12). Engage the parking brake whenever you plan on leaving the seat to prevent accidental movement of the sprayer. To engage the parking brake, pull up and back on the lever. To disengage, push it forward and down. If the sprayer is parked on a steep grade, apply the parking brake and place blocks at the downhill side of the wheels. Figure 11 1. Brake pedal 2. Accelerator pedal 18 smoothly. As soon as possible, push the control down to the Off position. A warm engine requires little or no choking. Range Selector The range selector, located to the left of the seat, has 5 positions: 3 forward speeds, Neutral, and Reverse (Figure 14). The engine will start only when the range selector is in the Neutral position. You must also fully press the brake with the sprayer stopped to change ranges. Figure 12 1. Parking brake lever Important: Do not shift out of or change ranges while the vehicle is moving. Attempting to change ranges while the vehicle is moving can damage the transmission. Only stopping the sprayer completely, and fully engaging the brake will safely disengage the locking pin and allow the ranges to be changed. Speed Limiter The speed limiter is a large knob located to the right of the seat (Figure 13). It allows you to set the maximum downward travel of the accelerator pedal, thereby limiting the maximum rpm of the engine. This indirectly limits the output of the sprayer. Note: The vehicle controls the application rate based on your speed and you do not need to keep a constant speed to apply at a constant rate. Figure 14 1. 2. 3.

Rotate the key clockwise to the Start position to start the engine and release it to the Run position when started. Rotate the key to the Stop position to stop the engine. Choke Control The choke control is a small knob to the right of the seat. (Figure 13). To start a cold engine, pull the choke control up. After the engine starts, regulate the choke to keep the engine running 19 Hour Meter The hour meter (Figure 14) indicates the total number of hours the engine has run. The hour meter starts to function whenever the key is turned to the Run position. Voltmeter The voltmeter (Figure 14) indicates the level of charge in the battery. When the battery is fully charged, the voltmeter will read in the center of the dial when the key is in the Run position with the engine off. When the engine is running the voltmeter needle should be to the right. Figure 15 1. Master boom switch Headlight Switch Boom Switches Toggle the switch to operate the headlights (Figure 14). Push it forward to turn the lights on and rearward to turn them off. The boom switches are located at the front of the control panel to the right of the seat (Figure 16). Toggle each switch forward to turn the corresponding boom section on and rearward to turn them off. When the switch is turned on, a light on the switch illuminates. These switches will only affect the spray system when the master boom switch is on. Neutral Engine Speed Lock Switch When the range selector is in the Neutral position, you can use the accelerator pedal to speed up the engine, then push this switch forward to set the engine at that speed. This is necessary to run the chemical agitation while stationary or operating attachments such as the hand sprayer (Figure 14). Important: The range selector must be in the neutral position for the switch to work. Fuel Gauge The fuel gauge is located on top of the fuel tank, on the right side of the machine and shows the amount of fuel in the tank. Master Boom Switch The master boom switch is located on the floor board of the machine cab and to the left of the operator. It allows you to start or stop the spray operation. Press the switch with your foot to enable or disable the spray system (Figure 15). When the master switch is off, the Spray Pro monitor screen reads “Hold." Figure 16 1.

This valve, located behind the tank (Figure 17), controls the amount of fluid that is routed to the booms by directing fluid flow to the booms or the bypass hose to the tank. You can control this valve in two ways: the application rate switch or manually. To control it manually, you need to disconnect the wire connector on the valve, then you can rotate the knob on top of the valve to manually obtain the desired pressure. Important: Only engage the pump switch when the engine is at low idle to avoid damaging the pump drive. Application Rate Switch The application rate switch is located on the control panel to the right of the seat Figure 16). Press and hold the switch forward to increase the spray system pressure, or press and hold it rearward to decrease pressure. Rate Lockout Key Switch The rate lockout key switch is located on the control panel to the right of the seat (Figure 16). Turn the key counterclockwise to the locked position to disable the application rate switch, thereby keeping anyone from accidentally changing the application rate. Turn the key clockwise to the unlocked position to enable the application rate switch. Figure 17 1. 2. Rate control valve Flowmeter 3. Boom valves Flowmeter Important: Do not attempt to move the range selector while the rate lockout key is engaged. Forcing the selector while moving will damage lockout key components. The flowmeter measures the flow rate of the fluid for use by the Spray Pro™ system (Figure 17). Boom Valves Boom Lift These valves turn the three booms on or off (Figure 17). If you do not have a boom installed or do not want a boom to be able to be turned on, you can manually operate each valve by disconnecting the wire connector in the valve, then rotate the knob on the valve clockwise to turn the valve off or counterclockwise to turn it on. The boom lift switches are used to raise the left and right boom respectively. Sonic Boom (Optional) The Sonic Boom switch is a rocker switch used to operate the Sonic Boom. Toggle switch forward for automatic, rearward for manual and center for Off. Boom Bypass Valves The boom bypass valves redirect the fluid flow for a boom to the tank when you turn off the boom section. You can adjust these valves to ensure that the boom pressure remains constant no matter how many booms are on. Refer to Calibrating the Boom Bypass Valves, in the Operation section. Foam Marker Switch Locations (Optional) If you install the electric boom lift, sonic boom, and foam marker kit, you will add switches to the control panel for controlling their operation. The sprayer comes with plastic plugs in these locations. 21 Agitation Control Valve Pressure Gauge This valve is located on the right side of the tank (Figure 18). Turn the knob on the valve to the 9 o’clock position to turn on the tank agitation and to the 3 o’clock position to turn off the tank agitation. The pressure gauge is located to the right of the tank (Figure 18). This gauge shows the pressure of the fluid in the system in psi and kPa. Use the gauge to adjust the by-pass valves whenever you change nozzles. Anti-siphon Fill Receptacle To the front of the tank cover is a hose receptacle with a threaded fitting, a 90 degree barbed fitting, and a short hose which you can direct toward the tank opening. This receptacle allows you to connect a water hose to it and fill the tank with water without contaminating the hose with the chemicals in the tank. Important: Do not lengthen the hose to allow contact with the tank fluids. Figure 18 1. Agitation control valve 2. Pressure gauge Note: For agitation to work, the pump must be on and the engine must be running above an idle. If you stop the sprayer and need agitation on, place the range selector in the Neutral position, set the parking brake, press the accelerator pedal to the floor, turn the pump On and turn the neutral engine speed lock On. 22 Spray Pro™ Monitor The monitor has an LCD screen that displays the data you select, a selection dial, and 4 buttons for calibrating the monitor (Figure 19).

Check the tire pressure every 8 hours or daily to ensure proper levels. Fill the tires to 18 psi (124 kPa). Also, check the tires for wear or damage. Think Safety First Add Fuel Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you or bystanders avoid injury. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. Before Driving the Sprayer for the First Time • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. Check the Engine Oil The engine is shipped with oil in the crankcase; however, the level of oil must be checked before you first start the engine and after you have run it. 1. Position the machine on a level surface. 2. Remove the dipstick and wipe it with a clean rag (Figure 20). Insert the dipstick into the tube and make sure it is seated fully. Remove the dipstick and check the oil level. • Never fill the fuel tank inside an enclosed trailer. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand. • Never smoke when handling gasoline, and stay away from an open flame or where gasoline fumes may be ignited by a spark. • Store gasoline in an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of gasoline. • Do not operate without entire exhaust system in place and in proper working condition. Figure 20 1. Dipstick 2. Filler cap 3. If the oil level is low, remove the filler cap from the valve cover (Figure 20) and pour oil into the opening until the oil level is up to the Full mark on the dipstick; refer to Servicing Engine Oil, Engine Maintenance, page 43 , for the proper oil type and viscosity. Add the oil slowly and check the level often during this process. Do not overfill. 4. Install the dipstick firmly in place. 25 In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. • Always place gasoline containers on the ground away from your vehicle before filling. • Do not fill gasoline containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge. Figure 21 1. Fuel tank cap • When practical, remove gas-powered equipment from the truck or trailer and refuel the equipment with its wheels on the ground. 3. Remove the fuel tank cap. 4. Fill the tank to about one inch below the top of the tank, (bottom of the filler neck). This space in the tank allows gasoline to expand. Do not overfill. • If this is not possible, then refuel such equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle. 5. Install the fuel tank cap securely. 6. Wipe up any fuel that may have spilled. • If a gasoline dispenser nozzle must be used, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Pre-Starting Checks Check the following items each time you begin using the sprayer for the day: Recommended Gasoline • Check the tire pressure. Note: These tires are different than car tires; they require less pressure to minimize turf compaction and damage. Use fresh, clean, unleaded regular gasoline suitable for automotive use (87 pump octane minimum). Leaded gasoline may be used if unleaded regular is not available. • Check all fluid levels and add the appropriate amount of specified fluids, if any are found to be low. Important: Never use gasoline containing methanol, gasoline containing more than 10% ethanol, gasoline additives, or white gas because engine fuel system damage could result. • Check the brake pedal operation. • Check to see that the lights are working. • Turn the steering wheel to the left and right to check steering response. Filling the Fuel Tank The fuel tank capacity is approximately 6 US gallons (21 L). 1. Shut the engine off and set the parking brake. • Check for oil leaks, loose parts, and any other noticeable malfunctions. Make sure the engine is off and all moving parts have stopped before checking for oil leaks, loose parts, and other malfunctions. 2. Clean the area around the fuel tank cap (Figure 21). If any of the above items are not correct, notify your mechanic or check with your supervisor Note: The fuel tank cap contains a gauge which shows the fuel level; check it frequently. 26 before taking the sprayer out for the day. Your supervisor may want you to check other items on a daily basis, so ask what your responsibilities are. Driving the Sprayer Starting the Engine 1.

Once you have it set, you can lock it at that setting by turning the locking ring at the base of the speed limiter clockwise until it stops (Figure 22). To release this lock, turn the locking ring counter clockwise until it is loose. 5. To release the speed limiter, press the button on the knob and lower it as far as possible. 4. If the engine is cold, pull the choke knob up. Important: Do not use the choke if the engine is warm. 5. Turn the key to the Start position until the engine starts. Important: Do not hold the key in the Start position for more than 10 seconds. If the engine has not started after 10 seconds, wait 1 minute before trying again. Do not attempt to push or tow the sprayer to start the engine. Stopping the Engine 1. Press the brake to stop the sprayer. 2. Pull the parking brake lever up and back to set it. 3. Move the range selector out of gear into the Neutral position. 4. Turn the ignition key to the Stop position. 5. Remove the key from the switch to prevent accidental starting. 6. Once the engine starts, push the choke knob down slowly. Driving 1. Press the brake pedal. 2. Push the parking brake lever forward to release it. 3. Move the range selector into the desired range. New Sprayer Break-In 4. Press the accelerator pedal to drive or press the brake to stop. To provide proper performance and long sprayer life, follow these guidelines for the first 100 operating hours: • Check the fluid and engine oil levels regularly and be alert for indications of overheating in any component of the sprayer. • After starting a cold engine, let it warm up for about 15 seconds before accelerating. • Avoid hard braking situations for the first several hours of new sprayer break-in operation. New brake linings may not be at Note: Stopping distance may vary depending on the sprayer load and speed. Setting the Speed Limiter 1. Press down on the accelerator pedal to obtain the desired speed. 2. Press the button on top of the speed limiter knob and pull up on it until you feel it touch the accelerator pedal, then release the button (Figure 22). 27 optimum performance until several hours of use has caused the brakes to become burnished (broken-in). is available in a formulation that would provide increased life to the sprayer, use this alternative formulation. • Avoid racing the engine. As always, remember to clean your sprayer thoroughly after all applications. This will do the most to ensure your sprayer has a long and trouble free life. • Vary the sprayer speed during operation. Avoid fast starts and quick stops. • Refer to the Maintenance section for any special low hour checks. Filling the Fresh Water Tank Operating the Sprayer Always fill the fresh water tank with clean water before handling or mixing any chemicals. To operate the Multi-Pro Sprayer first fill the spray tank, then apply the solution to the work area, and finally clean the tank. It is important that you complete all three of these steps in succession to avoid damaging the sprayer. For example, do not mix and add chemicals in the spray tank at night and then spray in the morning. This would lead to separation of the chemicals and possible damage to the sprayer components. The fresh water tank is located at the front, left side of the tank (Figure 23). It supplies a source of fresh water for you to wash chemicals off of your skin, eyes, or other surfaces in the case of accidental exposure. To open the fresh water tank spigot, turn the lever on the spigot. Chemicals are hazardous and can cause personal injury. • Read the directions on the chemical labels before handling the chemicals and follow all manufacturer recommendations and precautions. • Keep chemicals away from your skin. Should contact occur, wash the affected area thoroughly with soap and clean water. • Wear goggles and any other protective equipment recommended by the chemical manufacturer. Figure 23 1. Fresh water tank 2. Filler cap The Multi-Pro Sprayer has been specifically designed to have high durability in order to give it the long sprayer life you need. Different materials have been chosen for specific reasons at different locations on your sprayer to meet this goal. Unfortunately there is no single material which is perfect for all foreseeable applications. 3. Spigot Filling the Spray Tank Important: Ensure that the chemicals you will be using are compatible for use with Viton (see the manufacturer’s label; it should indicate if it is not compatible). Using a chemical that is not compatible with Viton will degrade the O-rings in the sprayer, causing leaks. Some chemicals are more aggressive than others and each chemical interacts differently with various materials. Some consistencies (e.g. wettable powders, charcoal) are more abrasive and lead to higher than normal wear rates. If a chemical 28 Important: Verify that the proper application rate has been set prior to filling the tank with chemicals. 9. Turn the agitation control valve to the 9 o’clock position to start agitation in the tank. 10. Add the proper amount of chemical concentrate to the tank, as directed by the chemical manufacturer. 1. Stop the sprayer on a level surface, move the range selector to the Neutral position, stop the engine, and set the parking brake. Important: If you are using a wettable powder, mix the powder with a small amount of water to form a slurry before adding it to the tank 2. Ensure that the tank drain valve is closed. 3. Determine the amount of water needed to mix the amount of chemical you need as prescribed by the chemical manufacturer. 11. Add the remaining water to the tank. 4. Open the tank cover on the spray tank. Operating the Booms The tank cover is located in the center of the top of the tank (Figure 24). To open it, turn the front half of the cover counterclockwise and swing it open. You can remove the strainer inside for cleaning. To seal the tank, close the cover and rotate the front half clockwise. 2 1 Note: For the following section to apply, you must obtain and install a boom kit and nozzles. Contact your Authorized Toro Distributor for information on the available boom kits and accessories. After you install your booms and nozzles and before using the sprayer for the first time, adjust the boom bypass valves so that the pressure and application rate remains the same for all booms when you turn one or more booms off. Refer to Adjusting the Boom Bypass Valves. The boom lift switches on the sprayer control panel allows you to move the booms between transport position and spray position without leaving the Operator’s seat. It is recommended to change boom positions while the machine is stationary. To change the boom position: 1. Stop the sprayer on level ground. G001897 2. Use the boom lift switches to lower booms. Wait until the booms reach the full, extended spray position. Figure 24 1. Tank cover 2. Anti-siphon ll receptacle 3. When the booms need to be retracted, stop the sprayer on level ground. 5. Add 3/4 of the required water to the spray tank using the anti-siphon fill receptacle. 4. Use the boom lift switches to raise the booms. Raise the booms until they have moved completely into boom transport cradle forming the “X” transport position and the boom cylinders are fully retracted. Important: Always use fresh clean water in the spray tank. Do not pour concentrate into an empty tank. 6. Start the engine, press the accelerator pedal to the floor, and set the neutral engine speed lock to the On position. Important: To prevent damage to the boom actuator cylinder, make sure the actuators are fully retracted before transport. 7. Set the pump switch to the On position. 8. Set the master boom switch to the Off position. The Spray Pro monitor will display “HOLD”. 29 The Boom Transport Cradle B. With the brake pressed, select the desired gear range then begin driving at maximum speed. C. Verify the monitor displays the correct application rate. If needed, manipulate the application rate switch until the monitor displays the desired application rate. D. Return to the location where spraying is to begin. 6. Set the master boom switch to the On position to begin spraying. The sprayer is equipped with a boom transport cradle that has a unique safety feature. In the event of accidental boom contact with a low overhead object while in the transport position, the boom(s) can be pushed out of the transport cradles. If this occurs, the booms will come to rest in a near horizontal position to the rear of the vehicle. While the booms will not be damaged due to this movement, they should be immediately put back into the transport cradle. Important: The booms can be damaged by transporting them in any position other than the “X” transport position using the boom transport cradle. Note: When the tank is nearly empty, the agitation may cause foaming in the tank. In this case, turn the agitation control valve to the 3 o’clock position to turn it off. Alternatively, you can use an anti-foaming agent in the tank (if compatible with the chemical you are using). 7. When finished spraying, set the master boom switch to the Off position to turn off all booms, then set the pump switch to the Off position. To put the booms back into the transport cradle, lower the boom(s) to the spray position, and then raise the boom(s) back into the transport position. Make sure the boom cylinders are fully retracted to prevent actuator rod damage. Spraying Spraying Tips Important: In order to ensure that your solution remains well mixed, use the agitation feature whenever you have solution in the tank. For agitation to work, the pump must be on and the engine must be running above an idle. If you stop the vehicle and need agitation on, place the range selector in the Neutral position, set the parking brake, press the accelerator pedal to the floor, turn on the pump, and turn the neutral engine speed lock On. • Do not overlap areas that you have previously sprayed. • Watch for plugged nozzles. Replace all worn or damaged nozzles. • Use the master boom switch to stop the spray flow before stopping the sprayer. Once stopped, place the range selector in neutral and use the neutral engine speed lock to hold the engine speed up to keep the agitation running. • You will obtain better results if the sprayer is moving when you turn the booms on. • Watch for changes in the application rate that may indicate that your speed has changed beyond the range of the nozzles or there is a problem with the spray system. Note: This procedure assumes that the pump is on from the Filling the Spray Tank procedure. 1. Lower the booms into position. 2. Set the master boom switch to the Off position. The Spray Pro monitor will display “HOLD”. 3. Set the individual boom switches, as needed, to the On positions. 4. Drive to the location where you will be spraying. 5. Turn the Spray Pro selection dial to the Application Rate position and use the application rate switch to achieve the desired rate. To do this: A. Ensure the pump is On. Cleaning the Sprayer Important: You must always empty and clean the sprayer immediately after each use. Failure to do so may cause the chemicals to dry or thicken in the lines, clogging the pump and other components. The rinse tank is located at the front, right side of the tank (Figure 25). If you install the optional 30 2 Rinse Kit, you can fill this tank with fresh water and automatically rinse the main tank, boom supply lines and nozzles. 3 1 Figure 25 1. Rinse tank (for use with the optional rinse kit, 106-4842) 1. Stop the sprayer, set the parking brake, place the range selector in the Neutral position, and turn off the engine. The tank will drain to left side of the machine. G005482 Figure 27 2. Locate the tank drain valve on the left side of the machine (Figure 26). The valve is on the frame in front of the fuel tank. 1. 2. Valve open Lynch pin 3. Valve closed 3. When the tank has drained completely, install the valve to frame with the lynch pin removed previously and close the drain valve (Figure 27). 4. Fill the tank with at least 50 US gallons (190 L) of clean fresh water and close the cover. Note: You can use a cleaning/neutralizing agent in the water as needed. On the final rinse, use only clean, clear water. 5. Start the engine. 6. With the range selector in the Neutral position, press the accelerator pedal to the floor and set the neutral engine speed lock switch to the On position. Figure 26 1. Tank drain handle Open the valve to drain any unused material from the tank and dispose of it according to local codes and the material manufacturer’s instructions (Figure 27). After draining, remove the lynch pin on the bracket securing the drain valve to the machine and let the valve rest on the ground . This allows any residual material in the line to drain. 7. Ensure that the agitation control valve is in the On position. 8. Set the pump switch to the On position and use the application rate switch to increase the pressure to a high setting. 9. Set the master boom switch and boom control switches to the On positions to begin spraying. 31 10. Allow all of the water in the tank to spray out though the nozzles. 11. Check the nozzles to ensure that they are all spraying correctly. 12. Set the master boom switch to the Off position, set the pump switch to the Off position, and stop the engine. 13. Repeat steps 4 through 12 at least 2 more times to ensure that the spray system is fully cleaned. On the last cycle, run the last few gallons of water through the drain valve to clear the drain tubing. 14. Clean the strainer; refer to Cleaning the Suction Strainer inCleaning, page 56. Important: If you used wettable powder chemicals, clean the strainer after each tank. 15. Using a garden hose, spray off the outside of the sprayer with clean water. 16.
